Hi Jesse,

I can't remember much of Robocode API but if you're only looking for
the closest robot, you don't have to keep them all (in an array or
other collection). You could just have two fields (String name; long
distance oslt) and on each ::onScannedRobot(...) you could check if
the distance to newly observed robot is smaller than smallest observed
so far. If it is, update name and distance values. Reset the values
between game ticks (turns, I guess). If you really want to look for a
min value in an array/collection, preferred idiom these days would be
to use Stream::min.

Best regards,
